Just a question to everybody. Is there anybody who is looking forward to use an entire convex bottom row on his/her planck? If there is no body, i might reduce these convex keys only for raise/lower and 2u key. Thanks in advance.
Personally, I find the idea intriguing. I don't know if it's my cup of tea, but I'd pay a few dollars more just to try it out.
As an Ergodox user I can see those convex keys being useful on the thumb cluster, too. I use 3 R1 keys for the topmost three keys there, so my guess is that if I don't like them in the bottom row, I can use them in the thumb cluster to have more prominent and easy to access keys. ((see attachment))
In short: I vote for versatility/expandability which is supposed to be a big yes for convex keys.
If you decide to cut it down, maybe 2-3 of each color for Ergodox/Planck users would be a nice addition. Knowing my preferences I'd take R1 as well as R4's.
